In this letter, concatenation of parity-check and polar codes is proposed to improve error correction performance. In addition, a heuristic construction of the parity-check-concatenated (PCC) polar codes is proposed. Simulation results show that the PCC polar codes with the heuristic construction have evident performance gains over the cyclic redundancy check-concatenated polar codes.
This paper provides analytical derivation for the average pairwise error probability (PEP) of un-coded multiband orthogonal frequency division multiplexing (MB-OFDM) system for Ultra wideband (UWB) communications. To capture the behaviour of UWB channels in terms of cluster arrival rate, ray arrival rate, cluster and ray decay factors, the Saleh and Valenzuela model is employed. It is shown clearly...
